* DESIGN CHOICES * I've chosen to stick with many of the core ParselTongue features excluding Objects and its GetField/SetField types. I have added the following core types: - CByte: maps to Racket strings (this will mean the interpreter will need to ensure the string passed to CByte represent the ASCII value of single bytes) - CByteArray: same as CByte except it is mutable - CList: maps to Racket vectors since Python lists are mutable - CTuple: maps to Racket lists since Python tuples are immutable - CRange: maps to Racket lists (the desugarer will need to generate the appropriate numbers based on the arguments passed to the method) - CDict: maps to Racket hash tables - CSet: maps to Racket vectors since Python sets are mutable - CFrozSet: maps to Racket lists since Python frozen sets are immutable - CClass: this will desugar to a function and therefore it's similar to a closure So, the values that can be returned are as follows: - VNum - VStr - VByte - VByteArray - VTrue - VFalse - VNone - VException - VList - VTuple - VRange - VDict - VSet - VFrozSet - VClass - VClosure * CODE STRUCTURE * The code structure hasn't altered from what was originally given to us on GitHub. The desugarer and interpreter follow the same style as what we did for ParselTongue. * TESTS PASSED * Types: test_floats.py test_comparisons.py test_booleans.py Scope: lambda1.py lambda2.py lambda3.py lambda4.py nearest-enclosing-scope.py nesting-global-no-free.py extra-nesting.py simple-nesting.py
